Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of image processing, and particularly relates to a pixel array control method and device and electronic equipment. BACKGROUND

[0002] In a complementary metal-oxide semiconductor (COMS) image sensor (CIS), there are two pixel exposure modes: rolling shutter and global shutter. Global shutter pixels are divided into charge domain global shutter and voltage domain global shutter.

[0003] In the related art, CIS widely adopts rolling shutter, and a pixel array control method thereof is that the first row of pixels first performs resetting, then enters an exposure stage, the second row of pixels performs resetting after the first row of pixels completes resetting, and then enters the exposure stage, and after the exposure stage ends, a reading stage is entered, and when signal processing of the first row of pixels is completed, a resetting period of the next frame is directly entered, and until all pixels complete signal processing. Due to the row-by-row staggered characteristics of the rolling shutter, CIS generally adopts a pixel control method of row-by-row scanning, but for a mixed pixel array that simultaneously outputs rolling shutter signals and global shutter signals, the above control method cannot be adopted. The pixel array control method of CIS adopting the global shutter is that pixels on all rows of pixels are uniformly reset, then uniformly exposed, and finally uniformly read. Due to the special control mode of the global shutter, for a mixed pixel array that simultaneously outputs rolling shutter signals and global shutter signals, the above control method cannot be adopted.

Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application. Figures 1-13 The pixel array control method, device and electronic device provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios.

[0033] The pixel array control method provided by the embodiments of the present application is applied to an image sensor, as shown in the figure, the image sensor includes a photoelectric module, a pixel array controller and a plurality of pixels distributed in an array, each pixel includes a rolling shutter module and a global shutter module. Wherein, the photoelectric module can convert light into electric charge, and the pixel array controller can control at least one of the rolling shutter module and the global shutter module by outputting different signals. Figure 1

[0034] As shown in the figure, the image sensor includes a photoelectric module, a pixel array controller and a plurality of pixels distributed in an array, each pixel includes a rolling shutter module and a global shutter module. Wherein, the photoelectric module can convert light into electric charge, and the pixel array controller can control at least one of the rolling shutter module and the global shutter module by outputting different signals. Figure 1 ​As shown, the pixel array can be an M*N array, each row or column of rolling shutter module is connected with the pixel array controller, and each row or column of global shutter module is connected with the pixel array controller. Each pixel in the pixel array receives control of the signal generated by the pixel array controller, wherein the signal for controlling the rolling shutter module includes a rolling shutter reset signal (RS_RST), a rolling shutter charge transfer signal (RS_TX), and a rolling shutter signal output signal (RS_SEL), the signal for controlling the global shutter module includes a global shutter reset signal (GS_RST), a global shutter charge transfer signal (GS_TX), and a global shutter signal output signal (GS_SEL), and a rolling shutter-global shutter charge transfer signal (RS_GS) for controlling the charge transfer from the rolling shutter to the global shutter, and the above signals are controlled to realize the reset, exposure and readout of the pixel in the rolling shutter / global shutter mode. Wherein, the RS_RST, RS_TX, RS_SEL, GS_RST, GS_TX, and GS_SEL signals are controlled by the pixel array controller in a row-parallel or column-parallel manner to access each row or column of pixels, all RS_GS signals are connected to the pixel array controller through a line, that is, global control, and the same RS_GS signal can be imported to all pixels at the same time.

[0035] As shown in Figure 2 , a flowchart of a pixel array control method provided by an embodiment of the present application, as shown in Figure 2 , the pixel array control method can include the contents shown in S101-S103.

[0036] In S101, the pixel array controller outputs a reset signal to at least one of the rolling shutter module and the global shutter module to control at least one row or column of pixels to reset.

[0037] Since the pixels can be row-parallel or column-parallel, at least one row or column of pixels can be controlled to reset. If the rolling shutter signal needs to be output, only the rolling shutter module needs to be controlled to reset, if the global shutter signal needs to be output, only the global shutter module needs to be controlled to reset, and if the rolling shutter signal and the global shutter signal need to be output at the same time, the rolling shutter module and the global shutter module need to be controlled to reset, which is determined by actual application.

[0038] In S102, after the reset is completed, at least one row or column of pixels that have completed the reset are controlled to expose to obtain charges.

[0039] After the reset is completed, the exposure phase is entered, which is performed on at least one row or column of pixels that have completed the reset, and the process can transfer the charges generated by the photoelectric module to the rolling shutter module or the global shutter module.

[0040] In S103, in a case where the exposure is completed, the charge is controlled to enter at least one of the rolling shutter module and the global shutter module, and the output signal of at least one row or column of pixels for which the exposure is completed is read.

[0041] After the exposure is completed, a reading stage is entered, and the output signal of the pixel is read.

[0042] It is worth noting that the sum of the time for any pixel to complete the reset, the exposure, and the reading in the above process is referred to as the time of one frame.

[0043] In the embodiment of the present application, the pixel array controller outputs a signal to at least one of the rolling shutter module and the global shutter module, controls at least one row or column of pixels to be reset, in a case where the reset is completed, controls the at least one row or column of pixels for which the reset is completed to be exposed, obtains the charge, in a case where the exposure is completed, controls the charge to enter at least one of the rolling shutter module and the global shutter module, and reads the output signal of the at least one row or column of pixels for which the exposure is completed. The embodiment of the present application controls the pixel to realize the rolling shutter function and the global shutter function through the pixel array controller, can control the rolling shutter module or the global shutter module through the pixel array controller output signal, and can also control the rolling shutter module and the global shutter module at the same time, without using two sets of control methods to control the rolling shutter module and the global shutter module respectively, so as to realize the independent control and the simultaneous control of the rolling shutter module and the global shutter module.

[0044] As shown in Figure 3 , the embodiment of the present application is based on the logical control method of the traditional rolling shutter, and the control logic of the global shutter is embedded in one frame of time, so that the rolling shutter module and the global shutter module can be controlled at the same time, and the rolling shutter module and the global shutter module can also be controlled independently. Using the scheme provided in the embodiment of the present application, the reset stage is the reset process of the traditional rolling shutter, and if the rolling shutter module output signal is controlled independently, the process is the same as the control method of the traditional rolling shutter. Taking N rows of pixels as an example, the control method of the rolling shutter module controlled independently is as follows, and the time sequence diagram is as shown in Figure 4 .

[0045] The RS_RST and RS_TX signals of the first row of pixels are pulled up to a high voltage level according to reset logic to reset the rolling shutter module and the photodiode (PD) in the pixel. The GS_RST and GS_TX signals control the reset of the global shutter module in the pixel, but since only the rolling shutter needs to be output, the global shutter module can be pulled up to a high voltage level to reset it or can remain at a low voltage level to not reset the global shutter module. The reset signals of the second row of pixels are the same as those of the first row, except that there is a time difference from the reset of the first row. According to the design requirements of the frame rate (equivalent to one frame time) of a user, the time difference can be less than, equal to, or greater than the reset time of the first row of pixels. This is similarly applied to the reset of the Nth row of pixels. After the reset of each row of pixels is completed, the rolling shutter exposure time is entered, during which the RS_TX signal of all pixels remains at a low voltage level to ensure that the charge generated by the exposure of the PD is in the PD. The RS_GS signal of all pixels remains at a low voltage level to ensure that the rolling shutter module and the global shutter module in the pixel are in a disconnected state. When the exposure period is completed, the first row of pixels enters the reading period first, and the RS_TX and RS_SEL signals in the pixel are transferred and read according to the logic. At the same time, some functions such as CDS (Correlated Double Sampling) are also completed during this period. The reading of the second row of pixels is performed after the exposure time of the second row of pixels is completed, and the reading step is performed with a time difference from the first row. According to the requirements and the design of the pixel signal processing link, the time difference can be less than, equal to, or greater than the reading time of the first row of pixels. This is similarly applied to the reading of the Nth row of pixels. After the reading of all rows of pixels is completed, the reset time of the next frame is entered, and the time of a frame is defined as the sum of the reset, exposure, and reading times of any row of pixels, and the sum of the times of any row of pixels is consistent.

[0046] If only the output of the global shutter signal needs to be controlled separately, only the control method of the global shutter needs to be implemented, and the reset process is the same as that of the rolling shutter control method, and is specifically as follows.

[0047] In a possible implementation of the present application, the pixel array controller outputs a reset signal to at least one of a rolling shutter module and a global shutter module to control at least one row or column of pixels to reset, which can include that the pixel array controller outputs a reset signal to the rolling shutter module to control the first row or column of rolling shutter modules to reset.

[0048] Correspondingly, the pixel array control method can further include: after a first preset time length after the first row or the first column of the rolling shutter module is reset, controlling the second row or the second column of the rolling shutter module to be reset until all the rolling shutter modules are reset.

[0049] Specifically, the control method for controlling the output signal of the rolling shutter module has been described in detail above, and will not be described again in the embodiments of the present application.

[0050] After the reset is completed, an exposure phase is entered. Specifically, in one possible embodiment of the present application, in the case where the reset is completed, at least one row or one column of pixels for which the reset is completed is controlled to be exposed to obtain charges, which can include: controlling all rows or all columns of global shutter modules to be reset at the same time after a second preset time length after the reset of the last row or the last column of the rolling shutter module is started; and in the case where the reset of all rows or all columns of the global shutter modules is completed, controlling all rows or all columns of the global shutter modules to be exposed, and controlling the charges generated by the photoelectric module to be transferred to the global shutter modules through the rolling shutter module.

[0051] That is, the reset phase of the global shutter module is started after a period of time after the reset of the last row or the last column of the rolling shutter module is started, and all rows or all columns of the global shutter modules are reset at the same time. After the reset is completed, all rows or all columns of the global shutter modules are exposed at the same time. That is, the global shutter module still follows the principle of simultaneous reset and exposure, but the control of the global shutter module is integrated into the control of the rolling shutter module in the present application, so that the independent control and simultaneous control of the rolling shutter module and the global shutter module can be realized.

[0052] After the exposure is completed, a reading phase is entered. Specifically, in one possible embodiment of the present application, in the case where the exposure is completed, the charges enter at least one of the rolling shutter module and the global shutter module, and the output signal of at least one row or one column of pixels for which the exposure is completed is read, which can include: in the case where the exposure of all rows or all columns of the global shutter modules is completed, the output signal of the first row or the first column of the global shutter module is read.

[0053] Correspondingly, the pixel array control method can further include: after a third preset time length after the output signal of the first row or the first column of the global shutter module is read, the output signal of the second row or the second column of the global shutter module is read until the reading of the output signal of all rows or all columns of the global shutter module is completed.

[0054] The reading in the embodiments of the present application is performed after the global shutter module exposure of all rows or all columns is completed, and the reading is also performed row by row or column by column, which is different from the reading of the traditional global shutter module, so as to be integrated into the control of the rolling shutter module.

[0055] Taking N rows of pixels as an example, the control method of the global shutter module is as follows, and the time sequence diagram is as shown in Figure 5

[0056] At the beginning of a frame time, the RS_RST and RS_TX signals of the first row of pixels are pulled high to reset the rolling shutter module and the PD in the pixel according to the reset logic. The reset signals of the second row of pixels are the same as those of the first row, except that there is a time difference in the reset of the first row. According to the design requirements of the user for the frame rate, the time difference can be less than, equal to or greater than the reset time of the first row of pixels. In this way, the reset of the Nth row of pixels is completed. It is worth noting that at the same time when the Nth row of pixels is reset, the RS_TX, RS_GS, GS_TX and GS_RST signals of all rows of pixels need to be pulled high at the same time according to the logical order. The purpose is to reset all global shutter modules of all pixels in the pixel array at the same time, and sample the charge signals generated by the PD during the rolling shutter exposure time (which is regarded as noise signal and buffered in the global shutter module after reset). After the global shutter module is reset, the global shutter exposure period starts. After the global shutter exposure period ends, the RS_TX signals of all rows are pulled high again to transfer the charge signals generated by the PD to the rolling shutter module. Then, the RS_GS signal is pulled high to transfer the signals, and enters the reading stage. In the reading stage, since only the global shutter signal needs to be output, the RS_SEL signal remains low. The reading mode of the global shutter signal follows the rhythm of the rolling shutter and uses a row-by-row reading mode, and the first row is read first. In each row, the GS_SEL is first pulled high to read and output the noise signals accumulated during the previous global shutter reset period and the global shutter exposure period. Then, the GS_TX and GS_SEL read and output the signals generated during the global shutter exposure period. After all rows of pixels are read, the next frame reset time is entered, and the time of a frame is defined as the sum of the reset, exposure and reading times of any row of pixels, and the sum of the times of any row of pixels is consistent.

[0057] If it is necessary to control the output of the rolling shutter signal and the global shutter signal at the same time, the rolling shutter signal needs to be output on the basis of the control method of the global shutter module described above, and the specific method is as follows. The reset process is the same as that in the control method of the global shutter module described above, and details are described above. The exposure and reading stages are as follows.​

[0058] In a possible implementation of the present application, in the case where the resetting is completed, the exposure of at least one row or one column of pixels whose resetting is completed is controlled to obtain the charges, which can include: in the case where the resetting of the first row or the first column of the rolling shutter module is completed, the exposure of the first row or the first column of the rolling shutter module is controlled, and the charges generated by the photoelectric module are transferred to the rolling shutter module.

[0059] Correspondingly, the pixel array control method can further include: in the case where the resetting of the second row or the second column of the rolling shutter module is completed, the exposure of the second row or the second column of the rolling shutter module is controlled, and the charges generated by the photoelectric module are transferred to the rolling shutter module until the second preset time length from the start of the resetting of the last row or the last column of the rolling shutter module, the resetting of all rows or all columns of the global shutter module is controlled to be performed simultaneously; and in the case where the resetting of all rows or all columns of the global shutter module is completed, the exposure of all rows or all columns of the global shutter module is controlled, and the charges generated by the photoelectric module are transferred to the global shutter module through the rolling shutter module.

[0060] In the embodiments of the present application, the exposure of the first row or the first column of the rolling shutter module is performed when the resetting of the first row or the first column of the rolling shutter module is completed, the exposure of the second row or the second column of the rolling shutter module is performed when the resetting of the second row or the second column of the rolling shutter module is completed, and the resetting of all rows or all columns of the global shutter module is controlled to be performed simultaneously until the second preset time length from the start of the resetting of the last row or the last column of the rolling shutter module. The exposure of all rows or all columns of the global shutter module is controlled to be performed when the resetting of all rows or all columns of the global shutter module is completed. That is, the exposure of the global shutter module is completed in the process of the exposure of the rolling shutter module, and the rolling shutter module and the global shutter module can be controlled simultaneously by the control method of the present application.

[0061] After the exposure, reading is performed. Specifically, in a possible implementation of the present application, in the case where the exposure is completed, the reading of the output signals of at least one row or one column of pixels whose exposure is completed by controlling the charges to enter at least one of the rolling shutter module and the global shutter module can include: in the case where the exposure of all rows or all columns of the global shutter module is completed, the reading of the output signals of the first row or the first column of the global shutter module and the output signals of the first row or the first column of the rolling shutter module is performed.

[0062] Correspondingly, the pixel array control method can further include: in the case where the exposure of the second row or the second column of the rolling shutter module is completed, the reading of the output signals of the second row or the second column of the global shutter module and the output signals of the second row or the second column of the rolling shutter module is performed until the reading of the output signals of all rows or all columns of the global shutter module and the output signals of all rows or all columns of the rolling shutter module is completed.

[0063] That is, the reading process is that the output signals of the rolling shutter module and the global shutter module are read at the same time in the reading mode of the rolling shutter module.

[0064] Taking N rows of pixels as an example, the control method of simultaneously controlling the rolling shutter module and the global shutter module is as follows, and a time sequence diagram is as shown in Figure 6

[0065] The control method of each signal is consistent with the above-mentioned global shutter separate output control method, and the only difference is that the rolling shutter signal needs to be output in this embodiment. Therefore, the RS_SEL signal needs to be pulled high to the high level for CDS sampling (if CDS is not performed, sampling is not needed during the rolling shutter exposure time period) and rolling shutter signal reading during the rolling shutter exposure time period. Similarly, the time of one frame is defined as the sum of the times of completing reset, exposure and reading of any one pixel row, and the sum of the times of any pixel row is consistent.

[0066] The embodiment of the present application integrates the control method of the global shutter into the control method of the rolling shutter based on the control method of the pixel array rolling shutter, and realizes independent control and simultaneous control of the rolling shutter and the global shutter. Since the control of the rolling shutter and the global shutter is completed within one frame of time, the pixel array controlled by the control method can realize rolling shutter signal or global shutter signal output within one frame, or dual output of the rolling shutter signal and the global shutter signal. The embodiment can also select noise reduction methods such as CDS to effectively reduce the noise in the rolling shutter / global shutter output signal.

[0067] In addition to the above-mentioned integration of the control method of the global shutter into the control method of the rolling shutter, as shown in Figure 7 The embodiment of the present application can also embed the control logic of the rolling shutter into the control method of the pixel array global shutter within one frame of time based on the control method of the pixel array global shutter, so that the control method of the present application can simultaneously control the rolling shutter module and the global shutter module, or independently control the rolling shutter module and the global shutter module. Using the scheme provided by the embodiment of the present application, the reset phase is the reset process of the traditional global shutter, that is, all rows or all columns are reset at the same time. If the global shutter module output signal is controlled independently, the process is the same as the control method of the traditional global shutter. Taking N rows of pixels as an example, the control method of independently controlling the global shutter module is as follows, and a time sequence diagram is as shown in Figure 8

[0068] ​​At the beginning of a frame time, the reset period, all the RS_RST, RS_TX, RS_GS, GS_RST, GS_TX signals of all the rows are pulled high to reset the rolling shutter and global shutter modules in each pixel. After the reset, the pixel array enters the global shutter exposure period. After the exposure is completed, the read time is entered. Since only the global shutter signal needs to be output, the RS_SEL signal remains low. The RS_TX signal and the RS_GS signal are pulled high to realize the transfer of the signal from the PD to the global shutter module. Then, the GS_TX and GS_SEL signals are sequentially pulled high according to the logic to realize the CDS function and the read output of the global shutter signal. Depending on the type of pixel signal processing architecture, if it is a row-parallel processing architecture, a row-by-row reading mode is adopted. If it is a pixel-parallel processing architecture, all the rows are processed in a unified reading mode. The time of a frame is defined as the sum of the reset, exposure, and read times of any pixel row, and the sum of the times of any pixel row is consistent.

[0069] If only the output of the rolling shutter signal needs to be controlled separately, only the control method of the rolling shutter needs to be implemented, which is the same as the control method of the global shutter, and is specifically as follows.

[0070] In a possible implementation of the present application, the pixel array controller outputs a reset signal to at least one of the rolling shutter module and the global shutter module, and controls at least one row or one column of pixels to reset, which can include: the pixel array controller outputs a reset signal to the rolling shutter module and the global shutter module, and controls all rows or all columns of the rolling shutter module and all rows or all columns of the global shutter module to reset at the same time.

[0071] Correspondingly, the pixel array control method can further include: sampling the first output signal of the rolling shutter module row by row or column by column after the reset of all rows or all columns of the rolling shutter module and all rows or all columns of the global shutter module is completed.

[0072] Specifically, the control method of the above-mentioned separate control of the global shutter module output signal has been described in detail, and will not be repeated in the embodiments of the present application.

[0073] After the reset is completed, the exposure stage is entered. Specifically, in a possible implementation of the present application, after the reset is completed, the at least one row or one column of pixels that have completed the reset are controlled to be exposed to obtain charges, which can include: after the reset of all rows or all columns of the rolling shutter module and all rows or all columns of the global shutter module is completed, the first row or the first column of the rolling shutter module is controlled to be exposed, and the charges generated by the photoelectric module are transferred to the rolling shutter module.

[0074] Correspondingly, the pixel array control method can further include: controlling the second row or the second column of the rolling shutter module to expose after a fourth preset time length after the first row or the first column of the rolling shutter module starts to expose, and controlling the electric charge generated by the photoelectric module to be transferred to the rolling shutter module until the exposure of all rows or all columns of the rolling shutter module is completed.

[0075] That is, the reset of the rolling shutter module is the same as that of the global shutter module, that is, all rows or all columns are reset at the same time, and when the reset is completed, the first row or the first column of the rolling shutter module exposes, and then a period of time, that is, the second row or the second column of the rolling shutter module exposes, and so on until the exposure of all rows or all columns of the rolling shutter module is completed. That is, the rolling shutter module still follows its exposure principle, but the control of the rolling shutter module is integrated into the control of the global shutter module, so that the independent control and simultaneous control of the rolling shutter module and the global shutter module can be realized.

[0076] After the exposure is completed, the reading stage is entered. Specifically, in one possible embodiment of the present application, when the exposure is completed, the control of the electric charge entering at least one of the rolling shutter module and the global shutter module, and the reading of the output signal of at least one row or one column of pixels exposed can include: when the exposure of the first row or the first column of the rolling shutter module is completed, the second output signal of the first row or the first column of the rolling shutter module is read, and the difference between the second output signal and the first output signal is taken as the output signal of the first row or the first column of the rolling shutter module.

[0077] Correspondingly, the pixel array control method can further include: reading the output signal of the second row or the second column of the rolling shutter module when the exposure of the second row or the second column of the rolling shutter module is completed, and so on until the reading of the output signal of all rows or all columns of the rolling shutter module is completed.

[0078] The reading in the embodiment of the present application is performed when the exposure of the first row or the first column of the rolling shutter module is completed, that is, the second output signal of the first row or the first column of the rolling shutter module is read when the exposure of the first row or the first column of the rolling shutter module is completed, and then the difference between the second output signal and the first output signal is taken as the output signal of the first row or the first column of the rolling shutter module. When the exposure of the second row or the second column of the rolling shutter module is completed, the output signal of the second row or the second column of the rolling shutter module is read, and so on until the reading of the output signal of all rows or all columns of the rolling shutter module is completed. That is, the rolling shutter module still follows its reading principle, but the control of the rolling shutter module is integrated into the control of the global shutter module, so that the independent control and simultaneous control of the rolling shutter module and the global shutter module can be realized.

[0079] Taking N rows of pixels as an example, the control method of the individual control rolling shutter module is as follows, and a time sequence diagram is as shown in Figure 9 .

[0080] Since the basis of this implementation mode is the global shutter control method, the global reset must be performed at the beginning of a frame, consistent with the global shutter control method described above. Then, RS_TX and RS_SEL signals are sequentially pulled high row by row to sample and output. The output sample signal is buffered on the pixel signal processing link, and this sample is completed to mark the beginning of the rolling shutter exposure time period. When the exposure is completed, the reading stage is entered. The reading stage also follows the reading mode of the rolling shutter, and RS_TX and RS_SEL are pulled high row by row for signal reading. The read-out signal is subtracted from the previously buffered sample signal in the pixel signal processing link to obtain the corresponding rolling shutter signal.

[0081] If it is necessary to control the rolling shutter signal and the global shutter signal to be output simultaneously, the pixel array controller control logic needs to implement the global shutter and rolling shutter control method, specifically as follows. The reset process is the same as that in the control method of the individual output of the rolling shutter module described above, and details are described above. The exposure and reading stages are as follows.

[0082] In one possible implementation of the present application, in the case where the reset is completed, the at least one row or column of pixels of which the reset is completed is controlled to expose and obtain charges, which can include: in the case where the reset of all rows or columns of rolling shutter modules and all rows or columns of global shutter modules is completed, the first row or column of rolling shutter modules and all rows or columns of global shutter modules are controlled to expose, and the charges generated by the photoelectric module are transferred to the rolling shutter module and the global shutter module.

[0083] Correspondingly, the pixel array control method can further include: controlling the second row or column of rolling shutter modules to expose and controlling the charges generated by the photoelectric module to be transferred to the rolling shutter module for a fourth preset time length after the exposure of the first row or column of rolling shutter modules starts, until the exposure of all rows or columns of rolling shutter modules is completed.

[0084] In the embodiments of the present application, the exposure of the rolling shutter module still follows its own exposure principle, that is, one row or one column is exposed at a time, and the exposure of the global shutter module also follows its own exposure principle, that is, all rows or all columns are exposed at the same time. The embodiments of the present application only fuse the exposure of the rolling shutter module into the process of global shutter exposure, that is, the exposure of the rolling shutter module is completed in the process of global shutter module exposure, and the rolling shutter module and the global shutter module can be controlled simultaneously by the control method of the present application.

[0085] After exposure, reading is performed, specifically, in one possible implementation of the present application, in the case that exposure of at least one row or one column of pixels is completed, reading the output signal of the at least one row or one column of pixels can include: in the case that exposure of all rows or all columns of global shutter modules is completed, reading the output signal of all rows or all columns of global shutter modules; in the case that exposure of a first row or a first column of rolling shutter modules is completed, reading a second output signal of the first row or the first column of rolling shutter modules, and taking the difference between the second output signal and a first output signal as the output signal of the first row or the first column of rolling shutter modules.

[0086] Correspondingly, the pixel array control method can further include: in the case that exposure of a second row or a second column of rolling shutter modules is completed, reading the output signal of the second row or the second column of rolling shutter modules until reading of the output signal of all rows or all columns of rolling shutter modules is completed.

[0087] In the embodiments of the present application, reading of the global shutter modules still follows the reading principle of the global shutter modules, that is, all rows or all columns are read at the same time, and reading of the rolling shutter modules also follows the reading principle of the rolling shutter modules, that is, one row or one column is read at a time. That is, reading of the rolling shutter modules is completed in the process of exposure and reading of the global shutter modules, and the rolling shutter modules and the global shutter modules can be controlled at the same time by the control method of the present application.

[0088] Taking N rows of pixels as an example, the control method of simultaneously controlling the rolling shutter modules and the global shutter modules is as follows, and a time sequence diagram is as shown in Figure 10 .

[0089] The control method of each signal is basically a combination of the above-mentioned global shutter and rolling shutter control methods. It is worth noting that, in the reading stage, the RS_TX signal is continuously pulled high to the high level until the RS_SEL is pulled high to the high level for reading of the rolling shutter signal. In addition, in the present embodiment, the global shutter exposure time in one frame is longer than the rolling shutter exposure time. Similarly, the time of one frame is defined as the sum of the time of completing reset, exposure and reading of any one pixel row, and the sum of the time of any pixel row is consistent.

[0090] The embodiment of the present application is based on a control method of a pixel array global shutter, integrates a control method of a rolling shutter, and realizes independent control and simultaneous control of the rolling shutter and the global shutter. Since the control of the rolling shutter and the global shutter is completed within one frame, the pixel array controlled by the control method can realize single-frame rolling shutter or global shutter signal output or double output of the rolling shutter and the global shutter signals. The embodiment can also select a noise reduction method such as CDS to effectively reduce the noise in the rolling shutter / global shutter output signals.
